PRESSURE-RELEASE FOR, GLOTHES-WRINGERS.

Application filed July 26, 1916. Serial No. 111,403.

To all whom it may concern:

Be it known that I, JOHN F. HEMENWAY, a citizen of the United States, residing at New York city, in the county of New York and State of New York, have invented certain new and useful Improvementsin Pressure-Releases foi C othes-VVringers, of which the following is a specification, reference beinghad therein to the accompanying drawing.

This invention relates to certain new-and useful improvements in pressure release for clothes wringers, the object being to provide a releasing device in which the movably mountedtop bar of the wringer frame operates the releasing means in order that the pressure on therolls canbe instantaneously released.

Another object of my invention is to pro vide a pressure release which is exceedingly simple and cheap in construction, and one which can be readily incorporated in the ordinary construction of clothes wringer now in use r Another object of my invention is to provide a movably mounted bar for the pressure screws held in position within the Wringer frame by an ex'pansible resilient member-carried by the top bar in such a mannerthat when the top bar is forced downwardly theresilient member is expanded in order to release the bar carrying the pressure screws.

Other and further objects and advantages of the invention will be hereinafter set forth and the no'vel features thereof defined by the appended claims.

r In the drawings,

Figure 1 is a side elevationof a clothes wringerframe in section showing the ap plication of my improved pressure release thereto.

- Fig. 2 is a perspective View of one of the members carried by the wringer frame .detached, and

Fig. 3 is a perspective view of an erid portion of the releasing spring and the guide member therefor.

Like numerals of reference refer to like parts in the several figures of the drawing.

In carrying out my invention; I employ a wringer frame 1 formed of slotted side bars 2 connected together at their lower ends by a rod 3 and connecting members 4. The upper ends of the slotted side bars carry a movably ings 12.

mounted top bar 5 which is slidably mounted within the slotted upper end portions of the side bars 2 in order to allow the same to move vertically within the side bars for the purpose hereinafter fully described.

Secured over the upper end portions of the side bars 2' of the wringer frame are channel members 6 which embrace the side bars 2 and extend upwardly beyond the upper end thereof, and are provided with horizontally disposed flanges 6 for limiting the upward movement of the top bar 5.

Mounted within the lower portions of the slotted side bars 2 are bearings 7 in which the shaft? of'the lower pressure roll 8 is mounted, said shaft being adapted to be driven by a crank or a drive pulley. Ar- ,rangedabove the lower pressure roll 8 is an upper pressure roll 9 carried by a shaft 10 mounted in bearings 11 arranged in the slots of the side bars 2, the shafts 7' and 10 being preferably provided. with meshing gears, not

shown, preferably inclosed by gear cas- Secured in the bearings 11 are spring sup: ports 13 on which are mounted the lower ends of the pressure springs 11 on the upper ends of which are arranged bearing plates 15 carried by a pressure bar 16, said plates being provided with depending stud portions 17 extending into the coil springs 14 for holding the pressure springs in their proper position within the slots of the side bar 2 of the wringer frame.

Slidably mounted in the slotted side bars 2 of the -wringer frame above the pressure bar 16 is a bar 18 which is rovided with threaded boxes 19- in which are mounted the threaded portions of the pressure screws 20, the lower ends'of which engage the plates 15. .The upper portionsof said pressure screws extend through openings 21 formed in the top bar 5 of the wringerframe so as to allow the top bar to move independently of the pressure screws forthe purpose hereinafter fully described. 2

In order to provide means for holding the intermediate bar 18 carrying the pressure screws 20 in a predetermined position so as to allow the pressure screws to'exert the proper pressure on the pressure springs, I

22 which is securedcentrally to the under side' thereof and projects through guide I members 23 carried by the underside of the top bar.5 which are in the form of angle brackets having their vertically disposed portions slotted to receive the spring 22, said springs being provided with slots 24 through which the pressure screws pass in order to allow the spring to have free movement independent of the screws. The channel members 6 are provided with slots 25 from the bottom walls of which project headed studs 26 adapted to cooperate with the key-hole slots 27 formed in the ends of the spring 22 so that when the wringer is in the position' shown in Fig. 1, the narrow portions ofthe key-hole slots 27 will be under the headed studs 26, of the channel membersfi so as to prevent upward movement of the intermediate bar 18.

When it is desired to instantaneously release the pressure on the pressure rolls in caseof accident by striking the top bar 5, the spring 22 will be elongated so as to bring the enlarged portions of the key-hole shaped slots 27 'invertical alinement with the headed studs 26'which will allowthe bar 18 to ingdownwardly on thetop bar, the spring can be placed in position over the headed studs so that the pressure screws can be tightened toeXert the desired pressure on the pressure rolls. 1 j Y From the foregoing description it will be seen that I have provided apressure release for clothes wringers in which the pressure screws are carried by the intermediate bar held in a predetermined position by a wringer frame and by a resilient expansible member carried by a movable top bar so that in order to release thepressureon the pres sure rolls, it is only necessary to force the top'bar downwardly.
